Just a thought - cats are supposed to hate the scent of cedar chips. I wonder if there is a safe (for cats and humans) cedar-scented spray around?

They hate vinegar too - spray some on, and it won't hurt the furniture. After a short time you won't smell it - but they still will!


I guess giving more attention to him when he is NOT clawing the furniture might help...but then you do have the others as well.

Good luck.
